While large-scale electrolyser integration enhances network stability by aiding constraint management and reducing renewable curtailment through storage, it also places considerable demand on electricity networks. This makes understanding the role of electrolyser deployment on distribution networks (DNs) increasingly crucial. While existing studies on hydrogen-integrated DNs often target specific operational costs or isolated constraints, they typically lack a comprehensive view that considers broader economic, operational, and environmental impacts. This study offers an extensive analysis across these dimensions, exploring diverse hydrogen supply configurations, including hydrogen pipeline and storage unit availability, within a real UK DN to provide a practical perspective. This study introduces a conflicting multi-objective function that improves load factor (LF) by 85.516% and reduces power loss by 22.947%, all while managing operational costs effectively. Findings underline that deploying electrolysers with efficient management algorithms can significantly enhance the operations of DNs.

Consequently, securing accurate and up-to-date data on actual carbon emissions emerges as a critical imperative. This study systematically reviews recent research on real-time carbon monitoring in the AEC industry from 2010 to 2024, focusing on key aspects such as monitoring object, boundary, dynamic data acquisition method, carbon calculation method, and functional services.

However, their integration remains limited, hindering fully automated real-time monitoring. Current monitoring systems primarily focus on carbon monitoring, neglecting potential for carbon prediction and early warning functionalities.
